Replacement PSU for HP Slimline s5-1128la

This 220W Flex-ATX power supply replaces the original HP 633195-001 unit in compatible Slimline desktops. It delivers up to 220 watts from a 115/230 V input and uses a proprietary form factor designed for low-profile chassis. The grey enclosure weighs 1 kilogram and includes the connectors required for the motherboard and drives.

Suits owners of the listed HP Slimline model

It fits the s5-1128la and other systems that accept the Bestec FH-ZD221MGR design. Builders needing higher wattage for discrete graphics cards or additional drive bays should look elsewhere, as the 220W limit and fixed connector set cannot support those upgrades.

220W capacity with fixed connector complement

The unit provides a 24-pin motherboard connector, a 4-pin CPU connector and two Sata power leads. This covers the board, processor and a pair of Sata drives. Systems requiring more than two Sata devices, PCIe power cables or a larger total power budget will exceed what this supply can deliver.

Questions about this item

Which motherboard power connector does the 220W Flex-ATX unit provide for the HP Slimline s5-1128la?

It supplies a 24 pin motherboard connector that matches the proprietary Flex-ATX layout used in the Slimline chassis.

Will the four pin and two Sata connectors run the existing hard drive and optical drive I plan to keep?

Yes, the four pin connector powers the hard drive while the two Sata connectors support Sata optical drives or SSDs you retain.

How can I confirm the replacement PSU is delivering stable power after installation?

The system should boot normally, the fan spins steadily, and the motherboard LED remains lit without unexpected shutdowns under load.
